Step-by-step explanation:
The correct answer is B) Bass clef. The bass clef is used to indicate notation that is relatively low in pitch. It is also known as the F clef. It is used mainly for instruments that have lower tones, such as bass guitar, cello, and the left hand of the piano.
In comparison, the treble clef (also known as the G clef) is used to indicate notation that is relatively high in pitch. It is used for instruments such as the violin, flute, and the right hand of the piano.
